10 Claims.

meter of the invention is adapted to indicate the A availability of a parking space for an automobile or other vehicle; upon actuation, to set, energize, and start timing means for indicating the permissibletimeinterval for or period of parking and, during the parking period, for indicating the time remaining in the parking period; andto indicate when the parking period has expired. In that manner the invention may be employed to facilitate enforcement of parking regulations.

A primary' objectv of the invention is the provision of a novel parking meter. Y

Important objects of the invention include the provision of such a parking meter of simple and fool-proof construction, which may be .readily installed and operated to indicate and time af desired parking periodand which. is adjustable to adjust the timed parkingperiod; which includes a parking period indicator, a grace period indicator, and an overtime indicator; which conceals the indicator means from view during the setting thereof; which during the timing operation reveals the time indicia at opposite sides of the casing; which employs coin controlled clock winding means that is automatically reset during the indicating period; which sets the indicator means from the clock winding means; and which employs a self-starting clock for driving the indicator means in accordance with the time indicia thereon.

Other objects of the invention include the combinations and arrangementsof parts as hereinafter described in connection with the accompanying drawings and as more particularly set.

Fig. 7 is a fragmentary sectional detail of the token or coin controlled device; and

10 Fig. 8 is an elevational view of the indicator means.

Illustrative of the invention, the novel parking meter comprises time indicatormeans I5, clock means I6 for driving the indicator means in ac- 15 depending boss 22 at its lower end, which is aper- 25 tured to receiver therein the upper end of a suit- Y able standard 23, preferably of hollow construction, for supporting the casing at a convenient height. 'I'he hollow standard 23 facilitates the mounting of a token or coin receptacle 24 with its open end communicating with the interior of the casing, and the receptacle extends through an aperture 25 in the lower wall of the casing into the hollow standard 23, as shown in Fig, 2.

y The casing is further provided with a pair of aligned sight windows 26 and 2l in the front and rear casing members, respectively, for rendering the indicator means I5 visible from opposite sides of the casing; with a pair of aligned sight windows 28 and 29 in the front and rear casing members, respectively, below the sight windows 26' o members for protecting the apparatus in the cas- 50 ing from the weather, and a key operable lock 33 at the upper end of the casing is employed for securing the rear casing member in closed position.

In order to permit replacements and repairs, 55

a mounting plate or panel 34 is removably mounted as at 35 in the front casing member I9 and serves to carry the indicator means and the operating and. control means therefor as a unltary assembly-Which is removable and replaceable by another such assembly while the rst mentioned assembly is being inspected, repaired, or othewise serviced. The plate 34 extends from below the'sight window 26 to the region of the sight window 26 and has an aperture 36 therein alinged with the sight window 26 and a shaft aperture 31 aligned with a shaft aperture 39 in and about centrally of the front casing wall.

The clock means I6 is suitably secured and spaced from the mounting plate 34 at about the center of the upper end thereof and may be of any usual or preferred type. Preferably, however, a self-starting clock is employed which has a timer shaft 39 extending rearwardly from oneV side of the clock means I6, and an energizing or winding stem 4I extending forwardly from the other side of the clock means. 'I'he winding stem 4I has xed thereon a gear 42 meshing with a gear 43 rotatably secured to the rear face of the mounting plate 34, as shown in Fig. 2, for winding or energizing the clock means I6 to cause it to rotate the timer shaft 39. In the illustrated clock, the timer shaft 39 and the winding stemI rotate together.

For the indicator means I5, we employ a disc 44 of, for example, sheet metal, fixed as at 45 to rotate with the timer shaft 39 and carrying a cirvcumscribing ring 46 of transparent orat least translucent material, such as Celluloid, and of suflicient width to extend from the periphery of the disc 44 to a position between the sight windows 26 and 21. The transparent ring 46 is secured as at 41 to the disc 44 for rotation therewith and is adapted to provide a parking period indicator 48, a grace period indicator 49, and an overtime indicator 5I by' dividing the ring into portions which may have different colors or may be otherwise diierentiated to designate the respective periods already mentioned.

Each of those portions of the ring 46 is calibrated in minutes or other time units in such a manner that the time indicia are visible from the front and rear of the parking meter through the sight windows 26 and 21. For example, at spaced intervals about the ring corresponding to ten minutes, the transparent ring may be opaqued with ink or other coloring as at 52, and the time indicia printed or otherwise inscribed thereon at both sides of the ring. During the operation of the indicator means I5 by the clock means I6, suitable stationary pointer means 53 cooperates with the time indicia to indicate elapsed time.

.f Associated with the indicator means I5 is a shutter member 54 which is pivoted on the rear end of a stud 55 projecting rearwardly from the mounting plate 34 at an end of the sight window 26, and which has a shutter portion. 56 forwardly -of the indicator means I5 and a shutter portion 51 rearwardly of the indicator means. The shutter member 54 is swingable about its pivot to and from a position between the sight windows 26 and 21 for concealing and revealing the time indicia from opposite sides of the casing.

For operating the shutter member 54, we employ link means including a link or an arm 58 pivotally connected at one end to an end of a link or arm 59 which is pivoted at its other end to a stud 6I projecting rearwardly from the mounting plate 34 above and at a side of the aperture 31. The arm or link 59 hasintermediate its ends an operating pin 62 operable from the token or coin controlled means I1 for raising, and holding in raised position, the shutter member 54 while the parking meter is being set, and for lowering the shutter member when the parking meter is set for operation. The shutter member is preferably painted the color of the overtime indicator 5I to remind a user of the parking meter not. to leave the parking meter until it is properly set.

In order that the cost of supervising parking regulations may be borne only by the users of the supervisory service, the token or coin controlledY means I1 is employed for driving the gear i3 to rotate the gear 42 and hence the winding stem 4I, thus rotating the timer shaft 39 to set the indicator means I5 at a position indicating the beginning of the parking period. In so rotating the winding stem 4I, the clock I6 is energized or wound for driving the indicator means in accordance with the time.indicia thereon. Such token or coin control means, generally considered, comprises an interrupted token or coin slide for delivering tokens or coins from the aperture 3i to an operative position and for delivering each token or coin, after it has served its control function, to the token or coin receptacle 24; a token or coin transferring device 63 (Fig. 5) for actuating the controlling token or coin during the clock energizing operation; and adjustable means 64 (Fig. 4) driven from the transferring device 63 for driving the gear 43.

The interrupted token or coin slide may be of any suitable construction and includes a receiving guideway 65 which is carried on the rear face of the mounting plate 34, and which communicates at one end with the aperture 3I and extends therefrom, at a generally downward inclination,

to a position above the token or coin transferring device 63 where the guideway 65 is provided with an outlet port 66. A depositing guideway 61 is carried on the rear face of the mounting plate 34 and has an inlet port 68 spaced vertically from the port 66 of the receiving guideway and at the opposite side of the transferring device, and 'communicates at its lower end with the receptacle 24.

For discouraging the use of counterfeit or spurious tokens or coins, the depositing guideway 61 is provided with aligned apertures 69 in its front and rear walls, andthose apertures 69 are aligned with the sight windows 28 and 29 and the aperture 36. At their lower sides the apertures 69 respectively communicate with generally rectangular apertures 1I in the front and rear walls of the guideway 61 for cooperating with a token or coin trip device or lever 12. The lever 12 is pivoted intermediate its ends on the stud 6I and is of curved configuration with a nger 13 at its lower end extending into the depositing guide or retaining a token or coin in view at the apertuies 69 until the next token or coin isV employed to 'control the parking meter. The lever 12 is yieldably held in its retaining position by a spring 14 and has at its end opposite the finger 13. a cam nger 15 operably engageable by a token or coin being transferred by the transferring device 63 for releasing the token or coin previously deposited, and held between the apertures 69 to permit that token or coin to fall into the receptacle 24.

'I'he token or coin transferring device 63 comprises a shaft or shank 16 which is journaled at its inner end in an offset arm of a bracket 11 secured as shown in Fig. 3 to the mounting plate 34, andfwhich passes through the apertures 31 and 88 to outside the casing. Outside of the casing, the shaft 18 is provided with a handle 18 to facilitate rotating the shaft. Forwardly oi Vthe supporting arm ofthe bracket 11, the shaft 18 carries a wheel-like member 18 (Figs. 6 and 7) rotatable therewith and having a hub 8l, a

A'shouldered 'cylindrical wall 82 spaced outwardly vus rcentrally of the spokes 84.

from and coaxially about the hub 8| and provided with an outwardly' extending peripheral flange 83, and a pair of oppositely extending, fiat spokes connecting the hub 8| and the cylindrical wall 82.

As shown in Fig. 7, the peripheral flange 83 is provided with a pair of diametrically opposite control slots 85 for receiving therein the operating pin 82 of the shutter member 54. When the pin 82 is in either of the slots 85 the shutter member is down below the sight windows 28 and 21 and the wheel-like member 19 is locked against rotation. When, however, pin 82 is raised to clear the flange 83, the shutter member 54 is raised to conceal the time indicia on the indicator means and the wheel-like member 19 may be rotated a half revolution until the pin 82 drops into the other slot 85. During that half-revolution of the wheel-like member, the flange 83 serves to hold the pin 82 in the position for keeping the shutter member 54 in the raisedposition to indicate that the parking meter is not properly set.

'I'he forward end of the cylindrical wall 82 carries a ring-likeI ratchet 88 having diametrically opposite positioning teeth or notches 81 cooperating with a spring-urged pawl 88 for positioning the wheel-like member 19 with respect to the pin 82. By reference to Fig. 3, it will be seen thatthe pin 82 is normally at the end of the slot 85 leading with respect to the direction of rotation of the wheel-like member, and is resiliently held in that position by the springurged pawl 88. The pin therefore prevents backward rotation of the wheel-like member. If while the pin 82 is in one of the slots 85, rotation of the wheel-like member is attempted in the direction of the arrow in Fig. 3, the lagging end `of the slotv 85 is brought against the pin 82, and

such rotation is stopped, the spring-urged pawl 88 returning the wheel-like member to the position shown in Fig. 3.

In that position of the wheel-like member 19, the oppostely extending, flat spokes 84 thereof are substantially vertical, and are aligned with and between the outlet port 88 of the receiving guideway 85 and the inlet port 88 of the depositing guideway 81. The cylindrical wall 82 between the forward face of the flange v83 and rearwardly ofthe ring-like ratchet 88 is provided with a pair of diametrically opposite slots 89 which are .normally aligned with the ports 88 and 88, respectively, outwardly thereof and with diametrically opposite recesses 9| in the hub 8| adjacent and The dimensions of the wheel-like member 19 are such that if the 'proper token or coin is inserted in either of the shaft 18 has loosely mounted thereon the adjustable means 84 which comprises a segmental gear92 meshing with the gear 43 and having a hub portion 93 extending rearwardly therefrom into the ring-like ratchet 88. gear may be spaced along the shaft 11 rearwardly from the mounting plate 84 by a suitable spacer or washer 94 and is adapted to be driven fron. the wheel-like member 19 by a pin or other projection 95 receivable in any of a plurality of pin receiving sockets 98 spaced arcuately about the shaft 18 and in the rear face of the hub portion 93. Thai; pin 95 extends from the hub portion 93 rearwardly between the hub 8| and the inner surface of the cylindrical wall 82 into the path of a token or coin carried by the wheel-like member 19 during the transfer of a token or coin to the depositing guideway 81.

In'the socket 98 shown in Fig. 4, the pin 95 is adapted to be driven by the token or coin being transferred sufficiently to bring the indicator means i5 to position to indicate a full parking period of say sixty minutes through the sight windows 28 and 21. By placing the pin 95 in one of the other sockets 98, it will not be engaged by the token or coin until after the token or coin has traversed a greater arc during the transfer to the depositing guideway 81 and therefore the segmental gear will be driven through a lesser arc than when the pin is in the position shown in Fig. 4. That driving Aof the segmental gear through a lesser arc results in bringing the indicator means to a position to indicate a parking period less than the supposed sixty minutes. In that manner, the parking period indicated and timed may be adjusted to suit various traflic conditions. It will be understood that after the parking meter has been set for timing and -indicating a parking period, the clock |8 may drive thewinding stem 4| and hence the chain'of gears 42, 43, and 92 in the opposite direction from that caused by the operation of the handle 18. In order to limit the rotation of the segmental gear 92 during such driving thereof from the winding stem 4|, and hence to determine-accurately the position of the indicator means I5 when the clock i8 is stopped,'the segmental gear 92 is provided with a lug 91 extending outwardly from its periphery for engagement with the lower end (Figs. 3 and 4) of a token or coin retaining member 98. If desired a pin or other'projection 99 on the rear face of the mounting plate 34 may be employed for engagement by the lug 91 to limit the rotation ofthe segmental gear by the handle 18.

The token or coin retaining member 98 is preferably of angular cross-section. It is mounted on the rear face of the mounting plate 34 and has a rearwardly projecting wall |8| which extends arcuately about a portion of the wheel-like member 19 outwardly adjacent the flange 83 from a position adjacent the cam finger 15 to a position adjacent the depositing guideway 81. vThe cam finger 15 thus extends rearwardly to adjacent the forward face of the flange 83 and is operable by the token or coin just before the outer portion of the tokens or coins periphery is engaged by the wall ||l| to retain the token or coin in the transferring device 83 while it is being transferred to the depositing guideway 81.

As already stated, until a token or coin is inserted in theaperture 3|, the handle 18 is locked against rotation. When a token or coin is in- That segmentalcess 9|. If the handle 18 is now rotated in the 75 direction indicated by the arrow in Fig. 3, the upper portion of the periphery of the token or coin will act as a cam to engage the pin 62 and raise the shutter member 54, whereby to conceal the indicator means l5 from view through the sight windows 26 and 21, the periphery of the flange 83 retaining the pin 62 in that position during further rotation of the handle 18.

Thus the token or coin serves to release the wheel-like device 19 as well as to raise the shutter member 54. Being thus released, the wheel-like device 19 may be further rotated by the handle 18 and carries with it the token or coin which next engages the cam finger 15 to operate the token or coin trip lever 12, releasing the token or coin last used to control the parking meter and permitting it to fall through the depositing guideway 61 into the token or coin receptacle 24. Continued rotation of the handle moves the token or coin beyond the cam nger 15, whereupon the spring 14 restores the trip lever 12, and into engagement with the pin in one of the sockets 96.

`further rotation of the handle 1B causes the token or coin to drive the pin 95 whereby to rotate the segmental gear 92 and hence the gears 43 and 42 for winding the clock I6 and setting the indicator means I5 at a position depending upon the socket 96 in which the pin 95 is located. The rotation of handle 18 is continued until it has been turned through degrees. When that has been accomplished, the token or coin passes beyond the lower end of the retaining wall I 0I and is aligned with the p'ort 68 of the depositing-guideway 61, whereupon the token or coin drops through that port into the depositing guideway and is stopped by the nger 'I3 in view between the apertures 69 through the sight windows 28 and 29.

At that position of the transferring device 63, the other slot 85 is in registration with the pin 62 which falls therein, thus lowering the shutter member 54 to expose the indicator means I5 through the sight windows 26 and 21 and locking the token or coin control means l1 against further rotation. When the token or coin falls into the depositing guideway 61, the segmental gear 92 is free to be rotated about the shaft 1li. The self-starting clock I6, energized as already described, now rotates the shaft 39 and hence the indicator means I5 in accordance with the time indicia on the latter to indicate the duration of. the parking period. That rotation is in the opposite direction from the direction described for setting the parking meter, and such rotation is transmitted through the stem 4I and the gears 42 and 43 to rotate the segmental gear 92 in the opposite direction until stopped by en'- gagement of the lug 91 with the lower end of the retaining wall IDI.

When the lug 91 engages the wall lili, the segmental gear is in its original position, the clock and hence the indicator means are stopped. Thus the clock in driving the indicator means resets the token or coin operated means for energizing the clock and resetting the indicator means. The foregoing cycle may be repeated as often as desired by inserting a token or coin in the aperture 3| and turning the handle 180 degrees in a clockwise direction as viewed in Fig. .1.
